Final Answer:<\/h3>\n\n\n\n

\u2705 Option (a)<\/strong>: Dipole-dipole in addition to dispersion<\/em><\/p>\n\n\n\n

This choice correctly corresponds to pair (a)<\/strong> \u2014 HBr and H\u2082S \u2014 which are both polar molecules capable of dipole\u2013dipole interactions along with dispersion forces.<\/p>\n\n\n\n

Explanation Summary <\/strong><\/p>\n\n\n\n

Intermolecular forces are attractions between molecules that affect physical properties such as boiling points and solubility. These forces vary based on molecular polarity, presence of ions, and size.<\/p>\n\n\n\n

In pair (a), HBr and H\u2082S are both polar molecules. Their intermolecular attraction involves dipole\u2013dipole forces<\/strong>, which occur when positive and negative ends of polar molecules attract. Additionally, London dispersion forces<\/strong> exist universally due to temporary electron fluctuations. Hence, both dipole\u2013dipole and dispersion forces are present.<\/p>\n\n\n\n

In pair (b), Cl\u2082 and CBr\u2084 are nonpolar. Nonpolar molecules cannot form dipole\u2013dipole attractions. However, temporary distortions in electron clouds lead to induced dipole\u2013induced dipole (London dispersion)<\/strong> forces, which are relatively weak but significant in large atoms or molecules like CBr\u2084.<\/p>\n\n\n\n

Pair (c) involves I\u2082 (nonpolar) and nitrate ion (charged). When an ion like NO\u2083\u207b approaches I\u2082, it can distort its electron cloud, leading to ion\u2013induced dipole interactions<\/strong>. Dispersion forces are also always present, making this a combination of ion-induced dipole and dispersion forces.<\/p>\n\n\n\n

In pair (d), NH\u2083 is polar and can induce a dipole in benzene (nonpolar). The result is an induced dipole\u2013dipole interaction<\/strong>, as benzene’s electron cloud is temporarily distorted by NH\u2083\u2019s dipole.<\/p>\n\n\n\n

Thus, the correct identification of interactions shows that option (a)<\/strong> best matches pair (a), making it the correct answer.<\/p>\n\n\n\n
